ATTACHMENT FOR WEAVING RIACHINES.

Application filed. May 22,

To all 10 I. out it WLttj/ concern Be it known that l. DANuiL Bnorinacu, a citizen of the United States. residing at hieene, in the county 0]: Cheshire and State of New Hampshire, have invented certain no i and useful Improvements in an Attachment tor Weaving li lacliines; and I do declare the following: to be a. full. clear. and er:- uct description oi the inventiom such as will enable others skilled in the art to which it appertains to make and use the sanie.

This invention relates to an improved attaelunent for weaving machines and one objcrt of the invention to provide a device which can be connected with the spool-carry.-

' inc frame and will serve to keep the threads under tension as they are drawn from the spools.

Another object oi? the invention to so construct this attachment that a separate tensioning means may be provided for each thread thus permitting: the threads to be l"1- d'iividually retained under tcnsioin extra str in upon any thread prevented from ha i any effect upon the remaining threads.

Another object oi? the invention is to so construct this attachment that the threa s while passing through the "frame will be pre vented from becorninc; tangled.

i\.ll)l]ll9l object oi the invention is to so construct this attachment that it can be read ily put in place in connection with a conventional construction of -"1)()Ol(1tt1lf]Ji1'15! board.

Another object of the invention is to provide a device oil? the character described which will be very el'l icient in operation and simple in onstruction.

This invention is illustrated in the 11690111- panvingz; drawings. wherein:

in n l is a view showing the device in front elevation and operativolv associated with a spool-carryin board.

l ure :3 is a view .aowinu: the structure l in side elevation.

Figure is a transverse sectional view taken along the line 5-5 o'l l.

lfligure 6 is a transverse sectional view taken along the line 6-43 of Fig. 4:.

This device is provided with side bars l which are preferably formed of solid bars of wood but may be formed of any suitable me- 1922. Serial no. 562,710.

terial. These side bars are provided with transversely extending passages 2 forming); spring pockets in which are positioned coiled springs 23 which have their outer ends secured to the side bars in any suitable manner, but in the preferred TfOlD'l will have them extended as shown in i2, and secured by tasteners such as small nails -1- driven into the outer sides of the side bars. These springs have their inner end portions provided with 5 with which the threads will be engaged as will be hereinafter brought out. These side bars are connected by means of strips 6 which extend between the side as shown in Fig. 6 and have their end portions reduced to provide finger or tcngitae extensions which are positioned in grooves 7 formed in the outer faces of the sidebars and secured by fasteners such as screws 8. Each oil these cross strips 6 is provided with thread passages 9 protected by bushings of china or other suitable n'laterial to protect the thread. and. each oi the cross strips carries brackets 10 which extend loi'igitudinally of the strips adjacent the thread passages 9 and-carry-eyes 11 to be engaged by the threads when the threads are properly threaded through the device. A bridge 12 formed of wire extends longitudinally of each cross strip so that the thread will engage these bridges and thus be protected from wear which might cause breaking or the thrimds. in addition to the cross strum-s (3, there has been provided. a head strip 13 which is somewhat similar to the cross strips (5 but is deeper than these cross strips and e tends beyond the plane of: the outer faces of the side bars so that this head strip can be provided with thread passages 1 which cor- .respond in number to the total. number of thread in all 011: the cross strips and will be provided with l'iushings similar to the bushings placed in the tl'iread passages ot the cross strig is. .l. roller 15 is mounted upon. an axle bar l6 which has its end portion-s bent to provide arms l? which are embedded in the lower ends (iii the side bars 1. It will, cit course, be ov .ious that if desired. stub pins embedded in the ends of the side bars may be used instead of a single bearing); rod.

When this attachnient is in use, it is to be connected with the board or creel 18 can rying the spools 19 upon which the thread 20 is wound. ln order to do so, the upper ends of the side bars 1 are provided with openings so that fasteners 21 may be passed thrtmgh the side bars and firmly hold the device in engagement with the board or creel 18. The threads from the different spools 19 are passed through the thread passages 14. of the head board 13 and are then carried downwardly. The threads engage the bridges 12 so that they are prevented from being worn against the upper edges of the cross strips 6 and pass over the roller 15 to the weaving machine. Each of the threads after being passed through a thread passage of the head board is carried forwardly and upon reaching the bracket of a selected cross strip is passed through the eye 11 carried thereby and is then passed through the eye of a spring carried by one of the side bars and then carried across the space between the side bars and through the eye of a spring directly opposite. After being passed through the eye of the second spring, the thread is passed through a thread passage 9 of the cross strip and is then carried downwardly over the bridges of the cross strips and over the roller. From an inspec tion 01. the drawings, it will be readily seen that when passing the threads through the tensioning device, the threads will be prefer ably carried forwardly in pairs and thus thethreads when carried forwardly to the eyes 11 will be positioned between the threads which have been passed through tie thread passages of the cross strips. The threads which are passing to the eyes 11 will. therefore be confined between threads which have already been engaged with the eyes of the tensioning springs and passed through the thread passages of the cross strips and tangling of the threads will be prevented. As the threads are unwound from the spools 19 during operation of the weaving machine, the springs will be stretched and therefore each thread will be held under tension and kept from running loose. The threads will further be prevented from being easily broken by an extra pull as the springs will. permit give and thus prevent breakage.

I claim:

1. A device of the character described con'iprising a frame for connection with a spool. carrying creel. said frame having thread passages at points throughout its length, bracket elements adjacent the thread passages, thread engaging elements carried by said brackets, and thread tcnsioning means at opposite sides of the frame for engaging threads after engagement with the bracketcarried thread engaging elements and before passage through the thread passages, and a cross head adjacent the upper end of said frame having thread passages corresponding in number to the total number of previously mentioned thread passages.

2. A device of the charm-tor described comprising a lrame for connection with a spool carrying creel, said frame having side bars and cross strips carried by and extend ing between said side bars and provided with thread passages. thread guidii'ig means connected with said cross strips. thread tensioning means carried by said side bars for engaging threads atter engagement of the threads with said thread guides, and a cross head carried by and extending between the upper end portions of said side bars and having thread passages corresponding in number to the total number of thread pas sages of the cross strips.

3. The structure of claim 2 and a bridge element extending longitudinally of the edge face of each cross strip.

1. A device of the character described comprising a Frame l iving side bars. cross strips .arried by and extending between the side bars and having thread passages. the side bars having transversely extending passages forming spring pockets. springs passing through the pockets and secured at their outer ends and having their inner ends tree and provided with thread engaging eyes. brackets carried by said cross strips and extending between said side bars. thread ongaging eyes loose upon said brackets, and a bridge element extending longiiinlinally ol' the edge taco oi. each cross strip.

5. The structure of claim l and an anti-- friction roller rotatably mounted beneath the frame and extending transversely oi the space between the side bars.

In testimony whereof l ha re hereunto sci. my hand.
